The study was conducted to investigate the community structure of superfamily Pentatomoidea(Geocorisae: Hemiptera) in Mt. Kyeryongsan from August, 1989 to August, 1990. The collected pentatomoid insects were composed of 34 species, 22 genera, and 5 families. Percentages of pentatomoid insects found in each observed zone were 45.4 % (22 species) in the paddy bank, 37.5% (26 species) in the weedy field and 17.0% (20 species) in the shrubs. Dominant species and Simpson's dominance indices were Eurydema rugosa and Carbula putoni ($\lambda$=0.125) in the paddy bank, Carbula putoni and Eurydema rugosa ($\lambda$=0.183) in the weedy field, Gonopsis affinis and Coptosoma biguttulum ($\lambda$=0.099) in the shrubs. Seasonal dom¬inant species were Eurydema rugosa and Dolycoris baccarum ($\lambda$0.207) in Spring, Carbula putoni and Eurydema rugosa ($\lambda$=0.1l5) in Summer, and Carbula putoni and Nezara antennata ($\lambda$=0.141) in Autumn. Species diversity indices(H') in paddy bank, weedy field, and shrubs were 1.034, 1.039, and 1.105, respectively. Evenness indices(J') were 0.770, 0.734, and 0.849, respectively. Community structures were almost similar between the weedy field and the shrubs.
